<span>Cone: A cone has a curved face and a flat face. The flat face is a circle, the curved face is a curved triangle. A sphere just has one curved face, which you cannot obtain from a 2D shape. The sphere is a ball and has the crosssection of a circle, which is a round shape with one side and no corners.</span>

Step-by-step explanation:
Both circles middles are positive
Answer:
angle(2) = 118 degree
angle(3) = 118 degree
angle(4) = 62 degree
Step-by-step explanation:
To find angle 2 :

The rule (head to head):
angle(2) = angle(3) = 118 degree
And the last one is angle(4) which is the same thing:
angle(4) = angle(1) = 62 degree

The upside down U means intersection
A intersect B intersect C is where all 3 circles overlap.
Sum up all the numbers to get 50
P (a intersect b intersect c) = 6/50 = 3/25
